Not exact matches

«Knowing how much force the microtubules and spindle exert on the kinetochore is very important because it's like a bridge,» Maresca says.

Biologists who study the mechanics of cell division have for years disagreed about how much force is at work when the cell's molecular engines are lining chromosomes up in the cell, preparing to winch copies to opposite poles across a bridge - like structure called the kinetochore to form two new cells.

Using two different force sensors to measure opposing forces inside dividing Drosophila cells, Maresca and colleagues at UMass Amherst have proposed that kinetochore fibers exert hundreds of piconewtons of poleward - directed force on kinetochores, settling the matter of how much force is brought to bear.
